Winterization, turned water back on

]I recently had my sprinkler system blown out by a professional for the winter. However, my outdoor water faucets are connected to the same water as the sprinkler system. I turned the outdoor water back on to be able to use the outside faucets for a few projects this weekend. By turning that water back on does that automatically fill my sprinkler lines? Will I have to get them blown out again? I wasn't sure if I could just drain the pipe out in my basement where my backflow preventer is located. My backflow preventer is located in my basement and is a FEBCO 825Y if that means anything.
